field. According to disklabel.h, its LFS semantics are "segment shift" (log2(segment size)), but in the code it is used nowhere, and there are even plans to allow non-poweroftwo segment sizes, so it won't ever work. While at this, simplify the disktab-like output routine... here, currently, BSDFFS, BSDLFS, EX2FS and ADOS do the same, so don't duplicate the code.
